Some cats do this due to prosencephalon disease, which is nothing to make light of. Hopefully some of these photos are random shots and not something the cat does for prolonged amounts of time.

My cat always did that when she was sulking.

Cats that put themselves in time out.

When cats do that it’s actually a neurological disorder and they need to be taken to the vet immediately when putting their heads on the wall like that. Poor things

How do you know they can’t see through walls?

Sorry to be a downer, but… If your cat does this, it could be a sign of Feline Vestibular Disease. Definition: Feline vestibular disease is a condition in which a cat suddenly develops incoordination, falling or circling to one side, involuntary darting of the eyes back and forth (nystagmus), a head tilt, and often nausea or vomiting. These clinical signs usually appear suddenly, many times in less than an hour. If you notice your cat doing this, please take them to a vet.

I’ve read that studies have shown that cats do that when they don’t feel well (i.e. a headache). Don’t know, I’m not a cat.
